The Beechcraft Super King Air family is part of a line of twin-turboprop aircraft produced by the Beech Aircraft Corporation (now the Beechcraft Division of Hawker Beechcraft). The King Air line comprises a number of model series that fall into two families: the Model 90 series, Model 100 series (these models comprising the King Air family), Model 200 series and Model 300 series. The latter two models were originally marketed as the "Super King Air" family, but the "Super" was dropped in 1996.
The Super King Air family has been in continuous production since 1974, the longest production run of any civilian turboprop aircraft in its class. It has outlasted all of its previous competitors and as of 2009 the only other aircraft in its class is the Piaggio Avanti. As of December 2009, the B200, B200GT and the larger B300 are the production models. Special mission derivative versions of these models are also available for order. The Beechcraft 1900 regional airliner was derived from the Model B200 King Air.
On 13 June 2005 Beechcraft announced at the Paris Air Show that it was developing the "King Air 350ER" version of the B300, an equivalent to the earlier Model 200T and B200Ts of the 200 series. Changes include an increase of MTOW to 16,500 lb (7,430 kg), provision for surveillance equipment in a belly pod, the landing gear of the Beechcraft 1900 to handle the increased weight and provide ground clearance for the belly pod, and extra fuel capacity in the engine nacelles to increase range (because of the B300s winglets it was unfeasible to fit wingtip fuel tanks as found on the 200T and B200T). On 11 November 2007 Hawker Beechcraft announced that the 350ER had been certified by the FAA.
In October 2008 Beechcraft announced updated versions of the B300 series, the 350i, with improvements to the passenger cabin. The manufacturer claims that the noise level and overall comfort of the King Air 350i, 350iER, 350iC and 350iCER are now competitive with those of light jets. The cabin of the B300 series has been updated with controllers in the passenger seat armrests that dim the LED lights, darken the windows and control an iPod dock and a high-definition video monitor. The cabin also includes Universal Serial Bus (USB) ports, AC electrical receptacles and fold-out tables for each passenger in the eight seats fitted. Deliveries commenced in December 2009.
